'flfoapllnvlwm itmwyroue. gli vBe l itknowultllat L JOHN ADAMS; :of Ifrvingtonyfinithe @G11-naef,.Westchester .and State of New York, have invented a newland useful Improvement in-Bermanent- Letter and PaperEileS.;.iai1dIdQ hiel-ela#,declareV the-giel: lowing to be'4 a fullpcleaiyand ,exactidescripj tion ofthe same, reference:-beng-fhadltothe accompanying drawin`g,eferming ,a arte; of'. this specication. .g The object of my invention is to produce a pelimanel'itwkletterf'ior.lpaper tile, in which4 the which permit the introduction.,between any two of them of anydesirednumber gofpapers,` letters, &c., whose edges may reach to the back ot' the sheets, and yet permit the whole to lie smooth, however much the quantity between any two sheets may exceed that between any two other sheets, the ends of said sheets being prevented from iying up and throwing or permitting the papers, &c., between them to fall out and it consists in the device constructed in the manner hereinafter set forth.

Figure 1 is a perspective view of my file with 011e part thereof removed. Fig. 2 isa perspective view of the le with the two parts together. Fig. 3 is a perspective view ot' the le with one portion inserted under the index or other leaves, showing the clip for holding them down. Fig. 4 is a sectional view of one part, to which the spring forming the clip is secured. Fig. 5 is a perspective view of a portion of one of the binding-leaves cut so as to form a means for holding it adjustably' in the tile. Fig. 6 shows a modification of the same, said means consisting` of a wire around which one end of the sheet is secured. Fi 6 is a perspective view of another niodiication of the same, a bar ot' wood or other material being used instead ot the wire shown in Fig. 6.

. A represents the lower part of the Iile, the sides B thereof being, on their inner surfaces, provided with grooves C and D, for the purpose hereinafter more fully set forth. The ends E otl these sides are formed, as shown in the drawing, with projections F and recesses G, and terminate near the middle of the bottom EL This latter is made of a width i eharaeteaorfmay remain plainindex or other sheets are adj-ustable,iand

A wire, extending part way or entirelyT across the end ofthe sheet, may form the projection or projections, as shown in Fig. 6; or they may be made of strips or bars of wood or other material, as shown in Fig. 7, or in Aany other convenient manner.

Ilhe sheets Kare placed in the-part A,their projection or projections L restingl in the groove or grooves C, which prevents them from being pulled out.

A strip, M, is secured so as to close up the tops of said groove or grooves, shown in the drawing as extending the whole width of the box. Instead of this, however, short strips can be used over the top of the grooveor grooves for this purpose, the object being to prevent the sheets from being moved out of.

the grooves. The form of the groove or grooves C, and that ofthe projection or projections L, may be varied, any form which will prevent the sheets from being withdrawn, except through the grooves C, being all that is essential for this purpose. The part Q of the tile, which forms the cover and extension of the sides of part A, is provided with a spring, P, as shown in Figs.2 and 4, which enables it to be used asa convenient desk-clip when desired. Its top O tits in the grooves D. Its sides R are provided with projections S and depressionsl, which correspond with and t into and over recesses G and projection F of Y the sides of part A, so as to form a secure lock and prevent the two part-s A and Q from being separated by excess of papers 'within or from any other cause.
